This series resolves an issue on PowerVM and KVM on Power where the memory the TPM log was held in may become inaccessible or corrupted after a kexec soft reboot. The solution on these two platforms is to store the whole log in the device tree because the device tree is preserved across a kexec with either of the two kexec syscalls. Regards, Stefan v2: - Added DT bindings patch (2/3) - Reformulated commit messages and addded Fixes tags - Follow Michael's suggestion on prom_init patch (1/3) Stefan Berger (3): powerpc/prom_init: Replace linux,sml-base/sml-size with linux,sml-log dt-bindings: tpm: Add linux,sml-log to ibm,vtpm.yaml tpm: of: If available use linux,sml-log to get the log and its size .../devicetree/bindings/tpm/ibm,vtpm.yaml | 20 +++++++++-- .../devicetree/bindings/tpm/tpm-common.yaml | 14 +++++++- arch/powerpc/kernel/prom_init.c | 27 +++++++++----- drivers/char/tpm/eventlog/of.c | 36 ++++++------------- 4 files changed, 61 insertions(+), 36 deletions(-) -- 2.43.0
